` SCRAPER.

Specification of Letters Patent. Patented Mar. 11, 1919.

Application led October 14, 1918. Serial No. 257,960.

To all lwhom t may concern:

Be it known that I, HENRY B. GERMES- HAUSEN, a citizen of the United States, residing at Woodland, in the county of Yolo and State ,ofV California, have invented certain new and useful Improvements in Scrapers; andI do declare the following to be a full, clear, and'exact description of the invention,

` such as will enable others skilled in the art vto which it appertains-to makeand use the same. This invention relates to Scrapers, andit *relates Vmorev particularly to an improved shown in Fig. 1;

rotary scraper such as employed for grading roads, etc.

One object of Y A further .obj ect-'is to provide for cushioning the shock consequent to the stopping of the rotary scraperelement, and to utilize portions of the main frame for backing the cushioning means; and

A further object is to provide a device of this character which is strong and rigid'and yet comparatively light.

Other objects and advantages may become apparent to persons who read theV following details of description in connection with the accompanying drawings, in which:

Y Figure 1 is a top plan view of a scraper 'constructed in accordance with the presentinvention;

Flg. 2 1s a side elevatlon of the device Fig'. 3 is a vertical horizontal sectional y view taken along the line 3-3 of Fig. 1;

Fig. 4 is a transverse vertical sectional view taken along the line 4 4 of Fig. 1;

Fig. 5 is a fragmental detail view illustrating stop-levers in a position at which the rotary scraper element is free from engagement therewith; and,

i Fig. 6 is ya perspective view showing the relation of'one of the stop-lugs to one of the stop-levers.,

Referring to these drawings in detail, in which 'similar reference characters correspond with similar parts throughout the several views, the main frame, which is indicated bodily by the numeral 7, consists of side beams 8, forwardly converging end beams 9, and cross rbeams 10, 11, 12 and 13.

The beams 8 to 13 inclusive are preferably formed of angle iron or steel, and the vcross beams are'cacb formed with apertured end y this invention is to proyidcl vfor generally improving' while vminimizing the cost-'lof devices of this/character;

n vided.

The main frame 7 is carried by wheels 15 'and 16, the former being pivotally mounted on an arm 17 which is pivotally mounted on the frame 7 atlS; and the wheels 16 are connected to the frame 7 by means of an axle 19 which has bifurcated ends 2O turned at .right angles to the middleY portion of the axle, bearings 21 being provided on the frame for this axle. A sleeve or hub 22 is secured on the axle 19 and carries a handlever 23 and a foot-lever 24, and by moving either of the levers 23 or 24:,the rear end 'of the frame 7 may be raised or lowered.

However, for convenience sake, the lever 23 is usually employed for raising or lowering the rear end of the frame while the footlever 24 is employed for holding the rear end of the frame temporarily in its raised position. A spring 25 has one end Lconnected to the lever 23 and has its other end connected to theV rear-end' of the frame 7, and this spring continually tends to throw the lever 23 rearward and thereby tends to force the rear end of the frame upward so as to regulate the depth to which a scraper element (hereinafter described) scrapes the earths surface. The lever 23 is held in different adjusted positions by means of two segments 26 having'apertures .27 therein and apin 28 seated alternatively in correspondu ing apertures. j

Approximately at `the central part of the frame 7 is provided bearings 29 in which a shaft 30 is mounted. This shaft carries a pair of wheels 31, and between these 'wheels is mounted a Scraper element 32 which has its ends secured to the wheels at 33 and is rotatable therewith.

Each of the scraper elements 32 comprises a plurality of wooden beams 34 1n parallel and juxtaposed relation to one another and constituting the body of the scraper element; a pair of excavating blades 35, the latter being set substantially at opposing tangente to the wheels 31; and,
